incredible new nano-technology diamond coating "Diamond Plus". This new innovative coating is recognized worldwide as the best non-stick coating. In Woll's new patent pending procedure, diamond crystals are heated to 36,032F/20,000C and blasted deep into the surface of the cookware using a plasma gun, forming an extremely hard base layer which is impervious to cuts and scratches. This diamond encrusted surface is harder and far more durable than the base layer used in most other premium cookware ranges. To this hard diamond base layer is added an anti-corrosive layer, then the primer and the final top coating that is infused with diamond crystals, and baked in at 450C. This ensures an extremely heat resistant and abrasion resistant non-stick coating, unmatched by any other coating on the market.
